OFFICE 1,964,362 SELECTIVE uomn DISPENSER Louis Nassif, Wheeling, W. Va. A t o Au ust .3 s r a 6 44 7 Claims. (01. 2.25 35) This invention relates broadly to devices for dispensing liquids, and more particularly to a device whereby any one of a number of liquids may be selectively dispensed from a single container. Obviously, the invention may be utilized to selectively dispense any one of a number of flavors or types of beverages, or, for instance, it may be used at automobile service stations for dispensing various grades or brands of oils and the like from a single container.

Another object is to provide a dispenser of the c ara t ib d ncludi m n w e y t e container may be efiectually sealed to the atmosp r w n n in e. thu to pr v??? v oration and chance of spilling.

Another object of the invention is to provide a device o e c ara m nti ned Wels i s mp e. c mp c a n p n i and 9 r adily usceptibl of e ti o t o o erat ng o der- A still further object of the invention is to provide a dispenser which may be refilled with liq id in an e tr me con eni nt man er- In d ribin t e ention in etail reigence is herein had to the accompanying drawings, in which Figure l is a vertical cross sectional View of the dispenser illustrating interior construction;

Figure 2 is a top plan View of the device, portions thereof being broken away for illustrative purp ses;

Fi ure 3 is. a sec iona i w t en 9 1 3+3 Fig 2, the air pump being shown in its depressed position.

Referring to said drawings, the reference numeral 1 designates a hollow cylindrical casing, made of metal, glass, or other appropriate material, haying an annular flange 2 formed on its lower end to provide a base. The casing 1 has extending vertically through the diainetrical center thereof an internal circular side wall 3, the same being formed integral with and connecting the top 4 and bottom 5 of said casing anddefining a circular opening 6 which extends throughout the entire height of said casing, the diameter thereof being made uniformly larger at a spaced distance from the bottom to form .a shoulder 7. A plurality of spaced radially disposed webs 8 are formed integral with the interior side wall 3 and extend therefrom to the circular exterior side wall 9 of the casing, the webs forming partition walls for a series of segmental compartments 10, which latter are designed to contain the liquid to be dispensed.

The top 4 of the casing has therein circular .openin ii. on such Op nin b n p qi ded eas rim n t Pu p e bein t u n s m an f hen t t e interior of achc m a i'e inent, as for'cle'aning, etc. Screw threadedcaps 12 are 'threadedl'y received in each of said open ings for closing the latter, said caps being maiiuallyrernovable whfill desired.

"Disposed rpr rotary'movement on the UPI??? 79 end of theeasing l" is a rotatable head 17 which, pfiferablyfha's a gtl ownwardly turned annular flange lddis'p osed 'in"n'onbinding relation to said casiing, as clearly shown in Figs. 1 and '3. Said head lflhas' formed integral therewith, on the under side thereof, adepending sleeve 19 whichin its assembled relation depicted "in the drawings is rotatably received in the Openings, the'lpwer'endbf'said sleeve being formed with screw threads and terminating at'a' spaced distance from the button; A'bushingZO is threadedlyatta" "d to 'th'e low'er end of the'sleevel 9 and interposed between the bushing 29 and the h ld 1 ei lii e e ve en' i li spiral spliilg 21 by means of'which tne e u 1,7 is mer er ess "yiel'din'gi'y "maintained inposition on the casing 1; at'thesame time'not nterferi'ng Twith "rotarymovements of the head jon i c i Q sii. t e bus 20 may h adjusted'as desiredfor placing the spring 21 un er greater or less'tension to increase or decreas the" ressure aiip'liedto the head '17 through the sleeve lg'ro'r regulating t e frictional resistance to'rotary movement 'ofier'ed between said'head "17 and th'top 4 of the easmg.

" The top 4 of the casing has iorrned in its upper face a plurality "qrsmau downwardly pressed indentations '22 of shbstantially' semi spheiifial form, said indentations being located i'n'regnlarly spaced'relation, one over each compartiiie t; and at edit-dis ant o nt r m hje axi of the'cylindrical casing 1. 'Also fo'rrnedin the under face of the overlying head His an aper- ,ture adapted to receive in the lower end thereof jasn allball' 24. said" aperture is threaded and ieceives at r a 's d 40. be ween wh h and the ball 25 is interposed a small coil spring25. As will be readily understood; the ball .24 and tl'iie iii i iaii i s izga i e i i p t w ori ti iiiii taining the head against chance rotary movement following movement thereof to an adjusted position over a selected compartment, as will hereinafter be explained. Tension of the ball 24 may be adjusted by means of the threaded spud and spring.

Provided intermediate the upper face of the top 4 of the container and the under face of the head 17, and stationarily afiixed to the latter, is a rubber sealing ring or gasket 26, the same being of such circumference that it overlies and normally seals the various sets of ports 13, 14 and 15.

The discharge spout 27 is formed integral with the head 1'7 and has a passage 28 extending therethrough normally terminating at its lower end in abutting air-tight relation with the sealing ring 26, a perforation being provided in the sealing ring at this point, as shown in Fig. 1, directly over and in register with the upper open end of the tube 16 located in the port 14 of the specific compartment from which liquid is to be dispensed, the head 17 being positioned accordingly.

A compression chamber 29 is located in the head, the same being somewhat in the form of a recess, the defining side wall of which is circular in top plan view. Provided in said chamher and designed to have vertical movement therein is a piston pump or plunger 30, the same being of hollow dome-like shape, as shown in section in each of Figs. 1 and 3. A piston rod 31 has its upper end attached to said plunger and is slideably received Within the embrace of the sleeve 19, the lower end being drilled and tapped to receive a large headed screw 32 adapted to retain said rod in position and providing means for limiting the upward movement of the piston in said sleeve. A compression spring 33 encircles the piston rod and normally maintains the plunger in its upward position. An air inlet port 34 affords access of air into the interior of the plunger, while an exhaust passage 35 leads from the chamber 29 outwardly and downwardly to a perforation located in the sealing ring, which perforation occupies registering relation to the port 15, as shown in Fig. 3, of the compartment from which liquid is to be withdrawn.

The operation of the device is as follows: Assuming that liquid is to be dispensed from a predetermined compartment, the head 17 is rotated on the dispenser casing 1 until the ball 24 registers with the indentation 22 of the selected compartment. Manual depression of the piston pump 30 and rod 31 against the tension of the spring 33 closes the inlet port 34, thereby trapping the air interiorly of the pump. Continued depression forces the trapped air outward from the chamber 29 through the exhaust passage 35 into the liquid containing compartment. As a consequence, the air pressure above the level of the liquid is increased which forces an amount of the liquid upward through the tube 16 and outward through the passage 28 of the spout 27. Upon release of the depressing pressure on the pump, the latter will be returned to its uppermost position by the spring 33, and the operation repeated.

In the described position of the head, the compartment diametrically opposite to that form which liquid is being dispensed is in position for ready and convenient filling. A filler spout 36 having a hinged cover 37 is formed integral with the head 17. Filler openings 38, two in number,

are located in the bottom or floor of the spout and register with two perforations provided in the sealing ring at this point, the latter perforations registering with the ports 13 and 14 of the compartment. The two ports 38 referred to are inlet ports and permit liquid introduced into the filler spout 36 to flow into the compartment by gravity. The remaining port 39 registers with dispenser casing port 15 and has extending upward therefrom a short length of tubing 41. This latter port 39 and associated tubing 41 acts in the capacity of an exhaust through which air displaced by the introduced liquid may escape from the interior of the compartment.

As is manifest, each of the compartments may contain a different grade, flavor or character of liquid, and the desired liquid may be dispensed from the container simply by positioning by rotating the pouring spout in association with the predetermined compartment or station, correct positioning being afforded by the ball and socket arrangement. Positioning the rotatable head so that the ball 24 occupies a substantially midway position between two indentations 22 seals each of the compartments, and eliminates chance of M evaporation or loss by spilling. 100

It will also be understood that the device, with a few minor changes in construction, may be adapted for use as an atomizer wherein the liquid may be dispensed in the form of a spray or mist.
